In order to analyze the impacts of the EWPO's on the strong EWPT parameter distributions,
we follow the procedure given in Refs. [1]}, [2]}, [3]}, [4]}
by defining a \(\Delta \chi ^{2}\)  as
\(\Delta \chi ^{2}_{\rm ewpo}=\sum _{i, j}\left(\Delta \mathcal {O}_{i}-\Delta \mathcal {O}_{i}^{\rm exp}\right)\left(\Sigma ^{2}\right)_{i j}^{-1}\left(\Delta \mathcal {O}_{j}-\Delta \mathcal {O}_{j}^{\rm exp}\right),\)
